Back in 2010, we were introduced to the fast-paced, gravity-flipping world of G-Switch, an action-packed platformer where the tap of a key caused the gravity of your perpetually running hero to invert, allowing them to run along ceilings, dodge obstacles, and sail across chasms... if you were fast enough. Now Serius Games serves up even more with G-Switch 2, which keeps the familiar gameplay intact, with polished visuals and its local multiplayer bumped from six to eight. As before, your character never stops running, so just click or hit any key you want to cause them to flip up and down on the screen, running along floor or ceiling (whatever that may be for the direction the track is going), and trying to avoid obstacles or plummeting to your death on your way to the forcefield-like checkpoints. If you hit something, it's not the end of the world unless you get knocked offscreen, and even then you'll just reload at the last checkpoint until you get it right. Some points along the track will speed you up, while others will slow you down, and if you're playing in Endless Mode, everything is procedurally generated. If all this sounds familiar, it's because it isn't substantially different from the original game, though it feels like it plays a lot more smoothly. It's still a lot of fun, and its funky soundtrack makes grooving through endless or multiplayer a treat, so if you're looking for simple yet snappy, reflex-based, high-score gameplay on your desktop, G-Switch 2 is worth tying on your running shoes for.
